Migration in Motion

Visualizing Species Movements Due to Climate Change

New research from the Nature Conservancy and university scientists revealed that only 41 percent of the natural land area in the United States retains enough connectivity to facilitate species tracking their preferred climate conditions as the global climate changes. As part of that study, scientists modeled the distribution and habitat needs of 2,903 vertebrate species in the Western hemisphere against land use and projected climate patterns.

The migrations in motion map provides a unique visualization of migratory patterns of birds, mammals and amphibians.

Conservancy cartographer and analyst Dan Majka brought this data to life in a series of maps that show what corridors mammals, amphibians, and other animals will use as they move to new habitats under projected climate change. Inspired by wind maps of the United States, and using code from Earth global wind map, adapted by Chris Helm, Majka’s dynamic map allows scientists and the public to see the continent-wide impact of climate change on animals and visualize corridors they will need to move.
